Rab proteins, a family of Ras-related small GTP-binding proteins, play a key role in regulating intracellular vesicle trafficking. Rab GDP dissociation inhibitor (GDI3) forms a soluble complex with Rab proteins and thereby prevents the exchange of GDP for GTP. Recently, two isoforms of Rab GDI cDNA were isolated from rats and mice. In this study, we have isolated a brain-type isoform of human Rab GDI cDNA and examined its expression in neuroblastoma. We tentatively designate it as human Rab GDI alpha (hu GDI alpha) and another human Rab GDI, as human Rab GDI beta (hu GDI beta)...
